-----------------------------------

             Summary: Flink SQL support S3 select
                 Key: FLINK-19595
                 URL: https://issues.apache.org/jira/browse/FLINK-19595
             Project: Flink
          Issue Type: Improvement
            Reporter: liuxiaolong


Flink is based on S3AInputStream.java to select datas stored in Tencent COS, it will call the getObject function of AmazonS3Client.java. 

Now, Tencent COS  have already support to pushdown the CSV and Parquert file format.

In these cases, using getObject to select datas will wastes a lots of bandwidth.

So, I think Flink SQL should support S3 Select, to reduce the waste of bandwidth.
